High-waisted panties, specially those so high-waisted as to cover the bellybutton at the front, and look even more weird as shit for our sober modern standards from the back, as if the wearer had a great problem letting even the smallest amount of fart to ever leave her, hence the name.

A person who cannot get their tongue further up the bosses / superiors / other persons arsehole. A kiss-arse. An arse licker. A rimmer. Someone who unnecessarily worships someone so much they catch their precious farts lest they be released into thin air.
